Measuring the hardness, strength, and toughness of steel

What are the differences between hardness, strength, and toughness, and what is their relationship?

Some materials are very hard yet brittle, with poor toughness and not necessarily high strength. Moreover, higher hardness may come at the cost of toughness. Containers often prioritize strength and toughness – it’s ideal to have high strength and low hardness, though this seems contradictory, as there appears to be a roughly linear relationship between strength and hardness
